As an update to clarify what the buildings are, what I'm making or have already constructed here's a breakdown of that photo:
The brown outlined structure is the station footbridge which I've mostly made and completed. It was demolished as part of the recent station rebuilding.
The black outline is a row of houses that have been demolished and not replaced and will be just a 'car park' on the layout so no need to model.
The dark blue outlined building is the Shipwrights Arms pub and house next door that still remains (grade II listed) and that I have already built.
The red outlined building is the SER office 'flat iron' building now demolished by Network Rail to have an open plaza but that I have already made.
The green outline is the corner buildings of Bermondsey Street and Tooley Street that are still there and I have already made.
The light blue is the office/shop block now demolished and replaced with a Hilton Hotel that I'm about to start making. It will be low relief hence the line going through the centre.
The purple outline is of buildings in Tooley street that I have little details of and have been demolished. I guess I will need to make them at some time.
All the buildings in the photo behind light blue structure have been demolished but will be behind the back-scene board line so won't need to be made as models. The chateaux style building to the right in Tooley street is still there and I will have to consider making that.
